The first moving images of 9/11 ringleader Mohamed Atta have surfaced, showing the murderous fiend laughing and smiling, and then reading his “martyrdom will” in Afghanistan.

Video of the terrorist at Osama bin Laden’s Afghanistan headquarters – almost two years before the attacks – was obtained by the Sunday Times of London and the newspaper says officials have confirmed its authenticity.

Atta, who flew American Airlines Flight 11 into the north tower of the World Trade Center, appears at a training camp in Afghanistan.

He is seen at one point laughing together with Ziad Jarrah, who unsuccessfully tried to pilot United Airlines Flight 93 into a target in Washington.

That jet crashed into a field in Shanksville, Pa., killing all on board after heroic passengers tried to recapture the aircraft from the hijackers.

The portion showing Atta and Jarrah is dated Jan. 18, 2000.

The Sunday Times received a copy of the video through what they called “a previously tested channel.”

While the word “will” can be seen the document Atta reads, the tape has no sound. The Times also said lip-reading sources were unable to determine what the terrorists are talking about, although they appear to be in “high spirits.”

Atta, the well-educated and groomed Egyptian, has a look of “quiet celebration,” according to the paper.

Jarrah, a lighter-haired middle-class Lebanese, jokes with him – both looking like college students.

They become serious only when each reads a document marked in Arabic “al wasiyyah,” which means “the will,” presumably a last testament on their plans to kill themselves and others for their deranged cause.

Atta and Jarrah have never been seen together before, and investigators have said that one of the keys to their success was completely avoiding each other while plotting in Germany and then in the United States.

Until now, investigators had not known where he had been in early 2000, but the tape shows he was in Afghanistan. The film also shows bin Laden talking to a crowd of about 100 of his followers at the mud-walled complex near Kandahar.

Sept. 11 plotter Ramzi Binalshibh is seen in the crowd, according to the Sunday Times – as is a bodyguard assigned to shoot bin Laden in the head twice if he was about to be captured.
